Features

Streamlined Angle Body Design: 

The unique angle body interiors are designed to minimize and prevent particulate build-up against the valve walls. With reduced fluid momentum change, particulate within the flow stream yield less impact energy against the valve, thus extending useful life in harsh service.

Heavy Guided, Hardened Plug Design: 

The heavy duty plug design of the 71000 series includes a solid stainless steel base material, with a hardened surface to prevent premature application induced erosion. Combined with optional flushing connections, the 71000 series is designed to prevent crystallization, or coke, build up, with a robust plug to break through any residual formation when equipped with high force actuation. Heavy port guiding.

Corrosion Resistance Materials: 

The 71000 Series is available for Severe Service Applications using materials and construction methods in accordance with ANSI/NACE MR0175/ISO 15156-1 & MR0103.g and stem guiding reduce trim vibration for longer installed life under severe service.

Low Emission Certification: 

Using the Masoneilan Low-E series of low-emission packing, the 71000 series achieves ISO 15848 Class A, and far exceeds EPA CLLT requirements of <100 ppm.

Tight Shutoff: 

Class IV leakage standard.  High thrust actuation options provided to meet IEC-534-60534-4 and ANSI/FCI 70.2 Class V.
